RAlL-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,959, dated January3, 1888.

Application filed May 2-1, 1887. Serial No. 239,179. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD 0. SMITH, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a certain new and useful Improvement in Bail-Sawing Machines,of which the following is a full, clear, and exact specification,reference being had to the accompanying drawings, forming part of thesame.

My invention relates to a certain improvement in rail-sawing machines;and the purpose of my improvement is to provide a means whereby thesaw-carrying frame can be readily set at any desired angle in order tomake an oblique cut on the-rail, and this I accomplish by making themain frame in two parts and swiveling them together, so that the upperpart can be turned in any direction desired.

In the accompanying drawings, which fully serve to illustrate myimprovement, Figure l is a front elevation of a railsawing machineembodying my improvement; and Fig. 2 is a top plan view of thestationary base portion, the other part of the frame being removed.

Let a represent the main frame as a whole, which is an elongatedrectangular frame provided at its lower end with jaws b b to receive therail 0, which is firmly clamped thereto by means of the threaded bolt01.

e is an inner frame or carriage fitted within the main frame a and soarranged as to slide up and down therein. The movement of this carriageis effected through a threaded shaft,

f, which is journaled to the carriage e, and

works through a threaded opening in the upper part of the frame a andterminates in a crank, g, by which it is rotated to lower the carriage.

Pivoted to the face of the sliding carriage e is a V-shaped frame, h,between the extended arms of which is secured the curved cuttingsaw 2".This frame is provided with upwardly and outwardly extending arn1s,whiehare made to terminate in socketsjj, into which are inserted handles orlevers 7: k, by which the frame h may be made to oscillate upon itsjournal bearing upon the carriage e. A pin, Z, is made to projectoutwardly from the sliding carriage 6 through a curved opening, at, inthe crossbar a of the saw-frame h, to regulate the to-andfro movement ofthe said frame. The oscillation of the saw-frame h is effected by themovement of the handles 7;, and the carriage is low ered by the rotationof the crank g. I may,

however, employ any one of the automatic sawfeed devices heretoforeshown in my previous applications, if desired, in place of thecrankmotion.

For the purpose of enabling the saw to make an oblique cut on the rail Iconstruct the main frame a of two parts, as a and a, the former of whichcarries the saw-frame and its operating mechanism and the latter thestationary or base frame to which the rail to be cut is se cured and onwhich the upper frame is made to turn. On the lower and upper faces,respectively, of the two parts a and a are provided side flanges, 0 0,and in each of these are formed curved slots 19 p, which receive theboltss,wit-h nuts 8', by means of which the two parts are securedtogether. In Fig. 2is shown a top plan of the base-frame a, showing theside flanges and curved slots, and the under and adjacent face of theupper frame is simi larly constructed. By loosening the nut the upperframe is set at any desired angle, so that the saw will make an obliquecut on the rail, as shown by dotted lines in Fig. 2.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a rail sawing machine, the combination, with a base frame adaptedto receive a rail, of a frame carrying an oscillatory cu ttingsawswiveled to said base-frame, as set forth.

2. A rail-sawing"machine consisting of a main frame carrying anoscillatory cuttingsaw and its operating mechanism, and adapted toreceive a railwayrail composed of two parts adj ustably securedtogether, whereby the saw can be set obliquely to the rail to be cut, asset forth.

3. The combination of the frames at and a, provided with the sideflanges, 0, having curred slots 19 and bolts and nuts 8 s, as and forthe purpose set forth.
